Ok, here's one fer you technical guys. I have a 72 with a 305 four barrel and it is acting worse than my ex wife!! Here goes. Normally the truck works fine but every once in a while it will just cut out and act like it wants to quit. It seems almost as if it is running out of fuel. It wont idle and I have to keep the rpm's up to keep it running. When it does quit the only way to restart it is to hold the accelerator to the floor and crank it . When it does restart it belches black smoke like crazy. It did this today and i kept driving it to get home and by the time I got home it worked fine!?!? I have replaced plugs, wires, checked the dist cap and rotor, it has a new fuel filter, everything seems OK. I even changed carburator still to no avail. Any ideas?
